For the past 3 weeks or so my Tohatsu 9.8 2-Stroke outboard has been acting up and I'm not sure what could be causing it.
When cold (more than 1 hour after the last run), I pull out the choke and it starts on the first pull and I immediately push back the choke. The engine idles nicely, and I give it a little bit of gas and put it into gear. I then slowly throttle up and the revs increase and then after 1-2 seconds the engine sputters and dies. I repeat the start process and on the 2nd or sometimes 3rd iteration the engine runs as before and I zip around with no problems.
Starting (without choke) when the engine is still warm is no problem, either.
I know I should take apart and clean the carburetor in any case, but I'm at a loss to figure out what is happening here. I can't tell if the engine is dying because of fuel starvation, too much air, or if the spark is missing.
